Panduit FS2EPKFLFNFM020 2F OM4+ Coded LC Patch Cord

Panduit FS2EPKFLFNFM020 Opti-Core 2-Fiber OM4+ Coded Fiber Patch Cord

The Panduit FS2EPKFLFNFM020 is a 20-meter duplex fiber patch cord engineered for high-speed 40/100G data center and campus deployments where physical layer security matters. Built on Panduit's Signature Core OM4+ technology with ultra-low insertion loss, this cord features coded LC connectors on one end and standard LC on the other—part of Panduit's keyed fiber system that physically prevents unauthorized connections. OFNP plenum-rated for air-handling spaces.

Key Features

• OM4+ Signature Core multimode fiber supports 40/100G Ethernet to 150m and 10G to 550m
• Coded LC duplex connector on one end—keys prevent insertion into uncoded adapters for physical layer access control
• Ultra-low insertion loss (typically <0.15 dB) for margin-critical 40/100G links
• OFNP plenum rating meets NEC Article 770 for air-handling spaces without conduit
• 20-meter length bridges cross-connect to zone distribution or equipment racks in datacenter hot/cold aisles
• Dark blue jacket and boots for OM4+ identification per TIA-598-D color coding
• 1.6mm zipcord cable construction balances flexibility with durability in high-density pathways
• Factory-terminated and tested—each cord ships with insertion loss test data
• RoHS compliant; 10-pack carton for volume deployments

The FS2EPKFLFNFM020 addresses a persistent datacenter challenge: how do you lock down fiber infrastructure when LC connectors are universal and unlocked? Panduit's coded fiber system solves this by machining a mechanical key into the connector ferrule housing—the coded end physically won't mate with a standard adapter unless you swap the adapter for a coded version. This creates an air gap at the physical layer: an attacker with a laptop and a patch cord can't just plug into your 100G backbone, because the geometry won't allow it. The system works across single-mode and multimode, so you can deploy consistent keying across an entire campus. The FS2EPKFLFNFM020 is a transition cord—coded LC on one end (typically the secure zone distribution panel), uncoded LC on the other (equipment port). Use it to connect untrusted devices to a secured infrastructure, or to bridge between coded and legacy uncoded zones during migration.

OM4+ Signature Core fiber is Panduit's enhanced bandwidth multimode—it meets OM4 specs (4700 MHz·km at 850nm) but with tighter manufacturing tolerances that push typical bandwidth above 5000 MHz·km. In practice this means you get more link margin on 40/100G SR4 optics, which translates to longer reach or better bit-error rate on marginal links. The ultra-low insertion loss (<0.15 dB typical, <0.25 dB max) matters when you're running 100GBASE-SR4 over parallel optics—each 0.1 dB you save in the channel is 0.1 dB more margin against aging, contamination, or temperature drift. The duplex LC interface is the de facto standard for 10/25/40/100G datacenter optics; the 2-fiber configuration supports all duplex protocols (10G SR, 25G SR, 40G BiDi). For 40G/100G SR4 (which requires 8 fibers), you'd use four of these cords or switch to Panduit's MTP-based solutions.

The OFNP plenum rating is non-negotiable for any cable running above a drop ceiling or below a raised floor in a commercial building—it's required by NEC Article 770 for optical fiber cables installed in air-handling spaces without raceway. OFNP compounds are engineered to limit smoke and flame spread; inspectors will flag non-plenum cable in plenum spaces, and it's a failed audit in BICSI DCDC or Uptime Institute Tier certification. The 1.6mm zipcord jacket is the right balance for patch cords: thick enough to survive abrasion in cable management arms and densely packed horizontal managers, but flexible enough to bend through the 25mm radius turns common in 1U patch panels. The 20-meter length is the longest single-piece factory-terminated cordage that ships without special handling—it's the go-to length for datacenter cross-connects (MDA to HDA), risers between floors, or campus pathways where pulling bulk cable isn't warranted.

Every Panduit Signature Core patch cord ships with serialized test data showing insertion loss measured at the factory on calibrated equipment. This matters for 40/100G link budgets—you know exactly how much loss the cord contributes before you install it, so you can calculate total channel loss and verify you're within the IEEE 802.3ba spec (1.9 dB for 40G-SR4, 1.9 dB for 100G-SR4 over OM4). Panduit's coded fiber system is compatible with all major adapter and panel vendors; you swap the adapter (Panduit CFFAFLC) into an existing panel, and the keying is active. The system supports TIA-604 FOCIS-10 (LC) geometry, so uncoded equipment ports work with uncoded cords as always—you're adding a layer of physical access control, not replacing the entire infrastructure. RoHS compliance covers lead, mercury, cadmium, and hexavalent chromium per EU Directive 2011/65/EU as amended. This cord is backed by Panduit's 25-year system warranty when installed per Panduit specifications.
